BD Quick Spool Valve Install with Pics

I bet post #1 has some underhood pics of the 6.5 with the QSV.. :hihi:

To be technically accurate, that's the BD Diverter Valve, not a QSV.:thumbsup:

Though they do the same thing, the actuator valves are different. The BD valve is boost operated and huge, as you know. The QSV valve is smaller and I was hoping that someone could tell whether it was vacuum operated.

Point being, there very likely is a QSV solution out there without the fitment problems of the BD Diverter Valve. Very few of us are interested in a quick spool solution that requires a new old radiator.
 
I'm thinking, based on that QSV, you could have a smaller actuator valve that would fit towards the front of the engine, thus solving just about all the fitment problems. Have it vacuum actuated giving purpose anew for the OEM vac pump. Gotta be some guys here willing to develop that.

The flange itself looks pretty standard. I don't know who does the butterfly valve fab/install and what's entailed with that. Does the valve have to be on a specific volute? The one to the outer/smaller part of the turbine wheel? If so, does that impact the actuator valve location?
 
I am missing the difference between a diverter valve and a quick spool valve? My "diverter valve" resulted in quick spool.
 
Also, I know a few people were talking about making homemade ones that fit directly inside the turbine housing. I feel that this could cause issues with heat expansion in the metal if not done properly. Am I correct? And about the issues of space, keep in mind this part was meant for a 5.9L Cummins. It would be great to get one made for a 6.5L but I don't see it happening. Somethings may just have to be changed.

I guess I was lucky in that I didn't have to swap radiators and I had already ditched the AC condensor (which makes getting to the downpipe a BREEZE lol) I know people are toying with how to make it better, but for now I think we just have to live with the changes that have to be made. And also maybe the QSV isn't made for everybody (I will call it what I want. It results in quick spooling. It's a valve. it's a quick spool valve)

In this application, i see them as being roughly the same. A large boost operated quick spool valve or a smaller vacuum operated quick spool valve. I think the concept of a large boost operated diverter valve or a small vacuum operated diverter valve also applies. Like I said, "It results in quick spooling. It's a valve. it's a quick spool valve"

You are correct on both counts one is boost operated the BD and the QSV is vacuum operated. There has been some discussion and work on one specifically for the A-Team Turbo, Just have not got something that is dependable, You have to remember it has to take the heat and right at that point it gets pretty hot at times. Even stainless will have issues at those temps, must be made out of something that will live at repeated high temps, cast works but then you have cost for the cast iron mold and set up, and really how many folks in the 6.5 community will spend the money? We have a reputation for being FRUGAL REAL FRUGAL. Now if a product saves you money it is justifiable.

What is a quick spool valve worth in the 6.5 community? The BD is a quality product, most wouldn't spend the money but the ones that did are happy. So could a guy make his money back on the cost to develop a good quality product ? Maybe just maybe.
 
I felt the BD valve was worth more than what was charged for it honestly. The BD unit is beyond quality. It is absolutely beautiful sitting in your hands and even better on the truck. I hate to say it but the radiator change and such is a small price to pay for something that is of that quality and works as well as it does

I believe you and agree a quality part is something to admire, not much craftsmanship left anymore.

I agree with you, the BD Diverter Valve looks like it's built solid and you've proven it works. Problem is, a lot of us in southern climes are not willing to give up AC or change out the entire radiator.

The only difference between the BD Diverter Valve and the QSV, other than the name, is the actuator. The purpose is the same. I was just using the industry marketing names to differentiate between the two. BD should be able to quickly swap their boost activated actuator for the vacuum activated actuator. They'd just have to change the bracketry. Everything else is common.

I'd spend the money for a drop in kit of the BD quality, not for something that requires new AC lines, new radiator, etc. The mods to make something like this work as a drop in for the 6.5 seem minor. I realize that anyone developing this has up front capital costs they must recover against uncertain demand from a dwindling and notoriously cheap population of 6.5 owners. The ATT has been a god send to the 6.5. A QSV for the ATT could take this to the next level. I just don't want to lose my AC or have to buy a '93 radiatior to do it.

From the time I learned of the QSV the first thing I thought of was to make it vac system operated. I think a push/pull cable could be the answer? Ive been real tempted to buy the BD and play with it. Pretty sure I could do the mechanical fabing, but would need someone to do the tune.

Push/pull cable as in manually actuated from the dash? Or cable from vacuum actuator? Not interested in the former, definitely interested in the latter. The latter would allow greater flexibility in placement of the actuator.
 
The 93 radiator doesn't seem all that bad. And warwagon did manage to have a new AC line made. You don't have to remove the AC. Just change the line. Mine wasn't charged and I never use it anyways. that is why i ditched it. It was just easier for me that way. I still think it was worth it to this day. Even running the large housing on the one volute is tremendously amazing with the new fuel changes.

Remove the big BD actuator. Push/pull cable to a remote vac control.
 
I didn't make a new AC line yet. I just recovered the system, rotated the line some to clear, changed the oring, and charged it back up. I may not need to do anything with it depending on how I do the air cleaner.

A small surge tank could be made or found off another vehicle. The battery could be relocated and the surge tank could go there. Again my 15 year old radiator had a cracked side tank so it needed to be changed anyway.
